ARTHUR ROGERS, OF BARNESVILLE, OHIO.

BOILER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 254,698, dated March '7, 1882.

Application filed January 4, 1882. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR Romans, of Barnesville, in the county of Belmont and State of Ohio,have invented certain new and useful Improvements in Boiler Cleaners; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon ,which form part of this specification.

Prior to my invention a perforated blow-off pipe for steam-boilers has been arranged in the bottom of the boiler, with its discharge end extended out through the wall of the boiler and provided with a cock,so that the sediment can be occasionally driven from the boiler. Ihave found, however, that this pipe cleans the boiler best at its end next to the discharge, the eflicacy of suchblow-off pipe diminishing as the distance from the discharge increases by reason of the obstruction within the pipe.

It is the object of my present invention to remedy such defect and to effectively clean the boiler along its entire length. This object I attain by means of one or more perforate pipes opening at opposite ends into a third discharge imperforated pipe, so that while one pipe will thoroughly carry off the sediment from one part of the boiler the remaining pipe will carry ofi all of the sediment which the first pipe may have failed to carry off from the other part of the boiler, as hereinafter described, and shown in the drawings, in which-.

Figure 1 is a longitudinal section of a steamboiler with myinvention applied thereto. Fig. 2 is a transverse section of the same.

A indicates the steam-boiler, and B B two perforated pipes arranged along the bottom of the same.

0 is the third unperforated pipe, which connects with a pipe, 0, passing through the wall of the boiler, and provided with the cock D for opening or closing the same. The perforated pipes connect by short pipes with this third pipe 0 at opposite ends-that IS to say, one perforated pipe. connects at one end with one end of the third pipe, and the remaining perforated pipe connects at its end with the other end of the third pipe. Hence those parts of the boiler not cleaned by one pipe will be effectively cleaned by the other.

To clean the boiler the cock is opened, so that the steam will force the water into the perforated pipes, carrying with it the sediment.

I am aware that it is not new in steam-boiler cleaners to employ perforated pipes arranged on the bottom of the boiler in combination with a blow-oil pipe and a cock.

What I claim is- The combination,within the shell of a steamboiler, of the imperforated pipe (3, one or more perforated pipes running parallel thereto and communicating therewith, a blow-ofl' pipe, and a cock applied to this pipe, substantially as described.

' In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

ARTHUR ROGERS. Witnesses:
